HOISTING-MACHINE.

Specification of Letters Patent.

Application filed October 25, 1905. Serial'No. 284,348.

To aZZ whom Lt may concern:

- Be it known that I, PAUL BAUOH, a-citizen of Hamburg, anda resident of No. 68 Schel lingstrasse, Hamburg, in the Empire of Germany, have invented a new, and useful .Hoisting-Machine, of which the following is a specification. 1 y

The present invention relates to an improved hoisting-machine which is driven by 1o friction gearing and in which the drivingwheel operates the drum by the agency-of intermediary'wheels, the latterimparting motion to a friction-disk fast to the drum? The object of my-invention is to afford a gs firm support for the various parts of a hoisting-machine of the kind referred to and to assemble said parts :in the smallest possible space. U Furtherobj ects of my invention are to simzo-plifyan'd' cheapen the construction and to 'render more efficient, serviceable, and durable in operation devices of the kind referred to.

'With these ends in view the invention consists inthe novel combination, arrangement, and adaptation of parts, all as more fully hereinafter explained, shown in theaccom- "panying drawings, and then specificallyjset out in the appended claims.

Figure :1 of the, accompanying drawings shows a longitudinal section of the hoistingmachine.

seen from the right of Fig. 1. Fig.. 3 shows, on an enlarged scale, the friction-gearing for imparting rotation to the drum. Fig. 4 shows, likewise on an enlarged scale, a centrifugal brake for the hoisting-drum.

Two standards a, secured together-by staying-rods b at their base ends, carry the shaft c, which is firmly keyed-in its bearings, so as to "be prevented from rotation. Loosely mounted 'on the shaft 0 is the drum d, which carries at one end and secured thereto by screws e or equivalent means the friction-disk 5- f, preferably of cupshaped cross-section, as

clearly indicated in Fig. 1. Loosely mount.- ed and freely rotatable on the shaft 0 is also the driving-wheel g. On the laterally-elongated nave h of the driving-wheel g is keyed a toothed wheel '11, a sheave, or like known power-transmission means.

Between the driving-wheel g and the friction-disk f are arranged intermediary wheels or, rollers 7c Z, which are supported, on the one hand, in the bearin -plate 'm, fast to the shaft 0, and, on the other and, in the bearing-plate Fig. 2 is a side elevation of same t, that is 'fixed to the aforesaid plate by screw-bolts 0. The rollers krun'oneccentoothed segment g, fixed to the shaft 19 exinion r, rotatable around the shaft 0. A

run on the shaft 8 under the weight of the IIO rotation of the drum. Referring to Fig. 4., said brake is of the centrifugal type. It comprises two brake-shoes 1 and 2, acting diametrically opposite against a stationary rim 14, which is fixed to the stationary bear- The other extremity carries a Weight 11,

adapted to be fixed at various distances from the fulcrum by means of the set-screw 12. A rod 13 connects both levers together, being pivotally attached thereto, as shown in Fig. 4. The centrifugal force created in the rotation of the disk f is counteracted by the springs 10 and the weights 11 until the speed of rotation becomes excessive, when the brake-shoes l and 2 will approach the stationary rim 14 and exert apowerful braking action by their frictional contact on said rim. The braking ower can be adjusted and adapted to the wor by varying the position of the weights 11 in regard to t e fulcrum of the two-armed levers.

By way of example I have shown in the drawings an electromotor 15 for driving the hoisting-machine, a pinion 16 on the shaft of the motor meshing with the toothed wheel 6.

I wish it to be distinctly understood that I do not confine myself to the details of construction shown in the drawings, but that I may carry out many modifications without departing from the spirit of the invention. For instance, instead of two pairs of rollers 7c Z I may em loy four pairs.

What I do claim as my invention, and desire to secure by Letters Patent, is

1. In a hoisting-machine, the combination of a stationary shaft, a drum loosely mounted thereon, a friction-disk fast to one end of the drum, a driving-wheel loosely mounted on the aforesaid stationary shaft, friction-rollers Jc, Z, stationary supports m, n affording bearings for said frictlon-rollers, the rollers k being keyed on eccentric shafts p while the shaft Z of the rollers Zis slidable axially in regard to the stationary shaft, means for throwing the aforesaid friction-rollers in and out of gear with the driving-wheel and the friction disk of the drum, and means for braking the drum, substantially as described and shown and for the purpose set forth.
